For example, clock_gettime() uses a timespec -structure which has two integer fields, tv_sec and tv_nsec, so the resolution -is 1 nanosecond. - -Precision ---------- - -The precision is the effective smallest difference between two timestamps of the -clock. It does not reflect the stability the clock rate. For example, -QueryPerformanceCounter() has a good precision but is known to not have a steady -rate. - - -Monotonic ---------- - -A monotonic clock cannot go backward. It may give the same value for two close -reads depending on the clock resolution. - -On Linux, CLOCK_MONOTONIC is a monotonic clock but its rate is adjusted by NTP. - -Steady ------- - -A steady clock is a clock with a stable rate. - -The `C++ Timeout Specification -`_ uses the -following definition: "Objects of class steady_clock represent clocks for which -values of time_point advance at a steady rate relative to real time. That is, -the clock may not be adjusted." - - Hardware clocks ===============
